Between the bodies I have, (Nikkormat FT2, EM, N80) I can use just about any F-mount lens.
The N80 is good for most any modern lens, but doesn't have the AI aperture coupling, so is near useless for older lenses.
What are some of the most compatible bodies? As in they can use (at least) AI and Non-AI lenses, and perhaps even autofocus and/or G lenses?
